Using The Touch Screen - United Screens Crystal Screens T-OLED User Manual

USING THE TOUCH SCREEN

You can use the touch screen to control your Windows (Mac, or Linux via external PC) operating system.
The Crystal Screens is HID compliant, delivering up to 10 points of touch on both Windows and Linux
without a driver. Single touch only is supported for Mac operating systems. There is no driver required to
enable Mac support.
DEVELOPING CONTENT
We strongly recommend you make use of the Crystal Screens Transparent Display Content Developer's
Guide at www.united-screens.tv/downloads
Use of this guide will both enhance the viewing experience of your Crystal Screens users and maximize the
life of the display.
Note: SBD – Stress boundary diffusion
The OLED has a „burn-in protection" against static contents, as the organic components in the display
would otherwise be subject to a faster aging process if a region were to be permanently illuminated. This
burn-in protection moves the image clockwise by one pixel at regular intervals to prevent this. However,
since this shift occurs only for the image and not for the touch overlay, there is sometimes a shift of up
to 13mm between the touch and the image. Therefore, the touch buttons/surfaces of Custom Made
Apps should be about 4cm in diameter (the larger touch surface can also be invisible, i. e. simply larger
than the visible button). This ensures that touch surfaces are always hit correctly. Furthermore, a distance
of approx. 2cm to the outer edge of the content area should be maintained to prevent the SBD from
„cutting off" the content. For Windows10 operating systems, a higher value for the size of text, apps and
other elements can be set in the display settings to increase the size of touch surfaces such as buttons, etc.
